Default Rhapsody Audio Issue

I really don't know if anyone here can help me as I have a very puzzling situation I'm dealing with in regards to listening to my music on Rhapsody. I've been on 4.4.2 ROMs ( Temacek and Carbon ) and i notice when i have the Rhapsody Equalizer on, once my screen goes black, the music stops playing. This was not an issue beforehand. i'm a bit puzzled by this. Was looking to see if there was an update for Rhapsody but nada. Has anyone else experienced something like this on Rhapsody or any other music streaming app? And if so, how did you solve the problem?
